请参阅我对这个问题的回答，以了解如何用更少的代码行完成它。这个方法允许你以任何你喜欢的方式动画一个新视图控制器的伪“Push”，当动画完成时，它就像你使用标准的Push方法一样设置导航控制器。我的示例允许您从左边或从右边对滑入进行动画操作。 为了方便起见，这里重复了代码:

-(void) showVC:(UIViewController *) nextVC rightToLeft:(BOOL) rightToLeft {
    [self addChildViewController:neighbor];
    CGRect offscreenFrame = self.view.frame;
    if(rightToLeft) {
        offscreenFrame.origin.x = offscreenFrame.size.width * -1.0;
    } else if(direction == MyClimbDirectionRight) {
        offscreenFrame.origin.x = offscreenFrame.size.width;
    }
    [[neighbor view] setFrame:offscreenFrame];
    [self.view addSubview:[neighbor view]];
    [neighbor didMoveToParentViewController:self];
    [UIView animateWithDuration:0.5 animations:^{
        [[neighbor view] setFrame:self.view.frame];
    } completion:^(BOOL finished){
        [neighbor willMoveToParentViewController:nil];
        [neighbor.view removeFromSuperview];
        [neighbor removeFromParentViewController];
        [[self navigationController] pushViewController:neighbor animated:NO];
        NSMutableArray *newStack = [[[self navigationController] viewControllers] mutableCopy];
        [newStack removeObjectAtIndex:1]; //self, just below top
        [[self navigationController] setViewControllers:newStack];
    }];
}

从示例应用程序中，可以看到这种变化。 https://github.com/mpospese/MPFoldTransition/

                                        }
     ];
}

- (UIViewController *)popViewControllerWithFoldStyle:(MPFoldStyle)style
{
    UIViewController *toController = [[self viewControllers] objectAtIndex:[[self viewControllers] count] - 2];

    [MPFoldTransition transitionFromViewController:[self visibleViewController] 
                                  toViewController:toController 
                                          duration:[MPFoldTransition defaultDuration] 
                                             style:style
                                        completion:^(BOOL finished) {
                                            [self popViewControllerAnimated:NO];
                                        }
     ];

    return toController;
}

我知道这个帖子很旧了，但我想我应该发表我的意见。你不需要制作一个自定义动画，有一个简单(可能是hack)的方法来做它。不使用push，而是创建一个新的导航控制器，使新的视图控制器成为那个nav控制器的根视图控制器，然后从原始的nav控制器中呈现出nav控制器。现在是很容易自定义的许多风格，不需要做一个自定义动画。

例如:

UIViewcontroller viewControllerYouWantToPush = UIViewController()
UINavigationController newNavController = UINavigationController(root: viewControllerYouWantToView)
newNavController.navBarHidden = YES;
self.navigationController.present(newNavController)

你可以随心所欲地改变演示风格。

这就是我总是设法完成这项任务的方法。

推动:

MainView *nextView=[[MainView alloc] init];
[UIView  beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[self.navigationController pushViewController:nextView animated:NO];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
[UIView commitAnimations];
[nextView release];

流行:

[UIView  beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
[UIView commitAnimations];

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDelay:0.375];
[self.navigationController popViewControllerAnimated:NO];
[UIView commitAnimations];

我还是从这里得到了很多反馈所以我将继续更新它，使用动画块这是苹果推荐的制作动画的方法。 推动:

MainView *nextView = [[MainView alloc] init];
[UIView animateWithDuration:0.75
                         animations:^{
                             [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                             [self.navigationController pushViewController:nextView animated:NO];
                             [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
                         }];

流行:

[UIView animateWithDuration:0.75
                         animations:^{
                             [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                             [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
                         }];
[self.navigationController popViewControllerAnimated:NO];

为推动

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
//transition.subtype = kCATransitionFromTop;

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController pushViewController:ViewControllerYouWantToPush animated:NO];

为流行

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
//transition.subtype = kCATransitionFromTop;

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController popViewControllerAnimated:NO];

@Magnus回答，只有Swift(2.0)才会这样

    let transition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionPush
    transition.subtype = kCATransitionFromTop
    self.navigationController!.view.layer.addAnimation(transition, forKey: nil)
    let writeView : WriteViewController = self.storyboard?.instantiateViewControllerWithIdentifier("WriteView") as! WriteViewController
    self.navigationController?.pushViewController(writeView, animated: false)

旁注:

你也可以用Segue做这个，只需要在prepareForSegue或shouldPerformSegueWithIdentifier中实现。但是，这也会保留默认动画。要解决这个问题，你必须转到故事板，单击Segue，取消选中“Animates”框。但这将限制你的应用在IOS 9.0及以上(至少当我在Xcode 7中这样做时)。

在segue中，最后两行应该替换为:

self.navigationController?.popViewControllerAnimated(false)

即使我设为false，它还是会忽略它。
